DNS vulnerabilites and Sydney IT Security Group.

As you may or may not have heard there was a big update released for basically the whole internet. See here and here for a test of your own dns.Basically it boils down to a bad guy being able to put incorrect entries into your ISP or works DNS cache that would point you to the wrong site. So instead of going to google.com it could take you to a hackers version, or whatever. This would also effect email.Now this kind of thing does happen occasionally, but this was seen as such a big issue (it could basically destroy the internet if unchecked and unpatched), that CERT who handles these issues let all the Vendors and developers know. Giving them time to write a patch for release on the same day. Very, very impressive.Not only Microsoft but Unix, Linux, BSD , Cisco, Checkpoint, all of them released a patch for their varied DNS implementations. Yahoo who uses an older *nix implementation of DNS, Bind8 managed to simply comit to abandoning it in favour of the newer patched Bind9.The question I put forward, is this finally a time of security as an institution. Security how it should be done, globablly. Sure it is still relying on Admins at the other end, but with Auto updates being the norm, it should be fine. This to me seems a step in the right direction, and I am sure even a couple years ago this wouldn't have happened. Will this one day lead us to a security utopia free of vulnerabilites and insecurites, no. But it may lead to sharing and assistance cross platform.Speaking of security, there is talk of an IT Security group being started up in Sydney, and I maybe taking the reigns. It will be sponsored by Microsoft but if I take the reigns I plan on being vendor neutral, all-be-it Microsoft has some nice claims to fame, and even with all their foibles and hatred that is flung at them, they do try and do some stuff right. Operating systems are tools, you should use the right tool for the right job.
